CARRIAGE-SPRING.

KQPECIFICATION forming part of Letters Patent No. 336,131, datedFebruary 16, 1886.

Application filed September 16,1895. Serial No. 177,242. (No model.)

To all whom it may concern:

Be it known that I, HoLLIs IV. MOORE, of Olean, in the county ofCattaraugus and State of New York, have invented certain new and usefulImprovements in Carriage and \Vagon Springs; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in carriage and wagon springs.

In Letters Patent N 0. 314,702, granted to me on March 31, 1885, acoiled wagonspring was shown and described, one end of which was adaptedto be firmly secured to the wagonbody, and the free end of which, or theend secured to the side bar, crossed the body end at or nearly at rightangles thereto.

The object of my present invention is to provide a spring of the samegeneral character as that described in the patent above re ferred to,butof such shape as to combine both torsional and compressional elasticityin supporting the weight of the wagon-body and its load.

\Vith this end in view my invention consists in certain features ofconstruction and combination of parts, as will behereinafter described,and .pointed out in the claim.

In the accompanying drawings, Figure 1 is a plan view of the spring;Fig. 2, a view in elevation.

A represents the spring, firmly secured to the wagon-body, as shown atc. The end a may be simply afiat-faced continuation of the body of thespring,or it maybe L or Tshaped to form a more extended bearing againstthe bottom of the wagon-body. From the point of attachment at a thespring extends grad: ually downwardly and outwardly toward the edge ofthe wagon-body, or beyond the edge; then curving, as shown at B, returnsbeneath the body without crossing itself then curving,

as shown at b, it extends outwardly, without 5 crossing itself, to thepoint of its attachment to the side bar, 0. The plan View of the springis therefore S-shaped, or composed of connected U-shaped bights. Thespring is preferably rectangular in cross-section, and gradually tapersfrom the body end a to the side bar end; but it maybe oval, semi-oval,round, polygonal, semi-polygonal, or any other desired shape incross-section, and may, iffound expedient, be made of the same sizethrouglr out. It will be readily seen that the application of weight onthe body end of the spring will,supposing the straight parts of thespring to be of rigid material,tend to twist the spring at the bights Bb, and so far the spring will act as a torsional spring; but as thestraight parts are in fact composed of spring metal, they will act ascompression-springs, and combine with the torsional elements to producean extremely easy and at the same time stiff and durable spring forgeneral use.

Itis evident that the forms above described may be attached to the axleor bolster on the axle as well as to the side bar, and thereby form endsprings instead of side springs.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A wagon-spring having the form of two or more semi-coils, substantiallyas shown and described, one of its ends being adapted to be firmlysecured to the wagon-body and the other to the side bar, at a point infront or back of a vertical plane passing through the point of itsattachment to the wagon-body, transverselyto the wagon-body,substantially asset forth.

In testimony whereof I have signed this specification in the presenceoftwo subscribing witnesses. A
